WINDOW CLEANER.

Specification of Letters Iatent.

Patented June 27, 1922.

Application filed November 6, 1920. Serial No. 422,331.

To all whom it may concern:

Be it known that I, CARL F. MUMAW, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Window Cleaner, of which the following is a specification.

This invention relates to window cleaning devices, it being the primary object of the invention to provide a novel window cleaning device designed to spray the window under treatment, means being also provided to rub the window to dislodge foreign matter therefrom.

A further object of the invention is to provide means carried by the device, for illuminating the surface under operation, to facilitate the cleaning thereof.

A still further object of the invention is the provision of portable means for forcing the water to the cleaning head, thus permitting the device to be employed in locations where the usual city water pressure is unavailable.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment ofthe invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 illustrates a plan view of the cleaner, and

Figure 2 illustrates a sectional view taken on line 33 of Figure 1.

Referring to the drawings in detail, the

cleaner includes a handle portion 5, and a head 6, the handle portion including a separable section 7 which is secured to the main or handle portion 5 as by means of the threaded coupling 8, the handle being hollow to permit fluid to pass therethrough.

The head includes a frame comprising the side sections 9 and 10 and end sections 11, the side section 10 being provided with a securing clip 12 adapted to embrace the handle section for restricting movement thereof, with respect to the head.

The handle section 5 has one end thereof extending beyond the side member 10 where the same is positioned within the removable section 13 which has connection with the transversely extending spray pipe 18, as by means of the T coupling 15, the pipe 14 having its ends secured to the end members 11 of the head as by the socket members 16.

This pipe 1 1 is provided with a plurality of openings 17 formed in the undersurface thereof, which openings spray water onto a surface under operation in a fine film to soften the foreign matter on the surface. Associated with the spray pipe 14 is a squeegee 18 which includes a strip of rubber positioned in a groove in the supporting member 19.

A pipe 23, which may be of any suitable construction, is positioned over one end of the pipe 24-, which is positioned within one end of the pipe 7 for supplying fluid to the cleaner, it being understood that the pipe 23, may be connected with any suitable source of liquid supply. Positioned on the supporting member 19 is an electric lamp 26-which may be supplied with electric current in any suitable manner, the lamp being for the purpose of facilitating the use of the cleaner in dark corners or at night.

Having thus described the invention, what is claimed as new is A window cleaning device comprising a head, said head embodying side and end sections, a pipe having its ends secured to the end sections of the head, said pipe having openings, the pipe being disposed adjacent to one of the side members of the head, a handle portion connected to the pipe intermediate its ends, said handle portion being hollow to direct fluid to the pipe, a relatively wide supporting member having connection with the end sections, and a squeegee carried by the supporting member.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

CARL F. MUMAW.
